> According to AMQP 0-10, in queue x-declare exclusive is not set and auto-delete is set,
the queue is deleted when all the
> consumers have finished using it.
> Howerver, I use example drain to test it:
> I set address above, then I run it ./drain -t 180, let me mark it node1
> Next, I login another terminal run ./drain -t 3, let me mark it node2
> After 3 senconds, node2 stop normally, but node1 print these results. I think the queue
link_2 should not be removed, because consumer on node1 is still exists.
